Managing Power Consumption
Managing Power Consumption
When you are not using your computer, you will want to maximize battery operating time without compromising performance. It is not necessary to turn the computer off in order to reduce power consumption and extend battery life.
Windows uses Advanced Configuration and Power Interface (ACPI) to provide manual and automated tools for reducing power consumption.
•You can set power management options to occur automatically, based on timeout values entered. See “To use automated power management” in the Reference Guide.
•You can also invoke power management options manually at any time by pressing the appropriate key. See “To use manual power management,” below.
To use manual power management
You can manage your computer’s power manually whenever you need to with any of the following three levels of power management.
